Introduction
This manual gives a clear understanding of how to set up, install and wire
the SE1 Smart Energy Switch. The SE1 is pre-congured to t most heating/
cooling systems that include boiler interlock, time/temperature control of
zone pumps, zone valves (with or without auxiliary switches) and domestic
hot water applications.
The SE1 is meant to work in combination with other MUONIO devices and is
not a stand-alone device.
For optimum system results, the hydraulic system should be installed and
functioning correctly.
IMPORTANT:
ONLY use 0.5 mm2 to 1.5 mm2 wiring cable when connecting to the SE1 unit.
Wiring external to the printed circuit board MUST be in accordance with current statutory
wiring regulations and any local regulations that apply.
The power supply must be 230 V~, 50/60 Hz, Single Phase. Attaching the SE1 board to
more than one phase will cause irreparable damage.
To ensure single phase, we recommend that power be introduced only at the mains
input terminals and that all other mains inputs be derived from suitable outputs
on the board itself.
Devices attached to the SE1 MUST be properly earthed in accordance with the
manufacturer’s specications. The method of connection to the mains electricity supply
MUST facilitate the complete electrical isolation of the entire installation.
A fused double pole switch, with at least 3 mm (1/8”) contact separation in both poles,
serving only the SE1 device should be used. The point of connection to the mains should
be readily accessible and, if possible, adjacent to the SE1 device.
WARNING & INFORMATION SYMBOLS
The addition of this symbol to a “Danger” or “Warning” safety label indicates
that an electrical hazard exists which will result in personal injury if the

equipment damage!
INFORMATION indicates an explanation containing information that is
useful to know, a supplementary operating procedure, or other data. The
Information symbol is used to address practices not related to physical injury
and to indicate where useful facts/tips will assist in installing or using the
device correctly.
